Now on, the complete run of the journal Experimental Musical Instruments, 1985-99. April 1989 has what appears to be only article ever written on making clay bells capable of good musical tones. You might have thought that there would be an entire cottage industry on making and understanding clay bells by now, among acoustic researchers, musicologists and crafts makers. But a search of Scholar and JURN, Google Books and Amazon, reveals absolutely nothing. “Ceramic bells” likewise. There’s a groundbreaking thesis topic there, if anyone wants it.
